Question
I have a 1986 mazda Rx7 and the only problem Im having is that sometimes while driving the car will start to buck and act like its gonna die

Answer
Josh,
  I am NOT qualified to answer this question but I will tell you that you will need to supply a lot more information about the car's symptoms to a Tech.  
  Has the "check engine" light come on? IF it has, you can go to O'Reilly Auto Parts and "rent" a scanner to see what the computer has stored.
  If the check engine light has not come on, the problems could include the computer, spark plug wires, distributor cap, rotor, ignition module, pick up coil or ignition coil.
  In your statement, you state: "sometimes while driving the car will start to buck and act like its gonna die".
  What you DON'T say is: Does it die? How does it run after it begins to buck? Does it do this when it is cold or when the engine is hot?
  I know I'm not helping but I'm trying to direct you to someone that is a Tech. These are the questions they will ask you. You will need to have the answers in order for them to assist you. As stated in my Profile, I'm NOT a Tech. I'm a Parts Professional. IF you need parts that are no longer available from Mazda, get the OEM part number from Mazda and I can attempt to locate it for you.
  I hope this is of some assistance and good luck..
